And actually the DC distribution system was more common than you think.
I recently was up at the Mt. Wilson observatory and was inside the 100-inch
telescope dome. ALL of the controls for the telescope, the dome slit motors
(the ones that slide the panel open the telescope to look through), the d
We had our fill of those here, too. The "hot" side of the AC line (if you were
lucky, polarized plugs were rare in those days) was connected directly to a
35W4 or some such half wave rectifier tube and later to a selenium half wave
rectifier with the other side of the AC line being connected

That's the best way, and we did do that, but it can be useful to float some

Very nice explanation of the issue.
Just to clarify a point or two, industrial users benefit directly from PF
correction of their plants largely because the utility supplier either: a.
doesnt' penalize them for low PF, and/or b. credits them for PF above say .90.

When in comes to matters of science, there will always be some who step forward
with anecdotal 'evidence' that they have experienced something that contradicts
accepted scientific knowledge. Using caps to reduce your power bill is one of
those myths. Your power meter is a true watt meter, a
